Abstract
An antenna system is disclosed that includes a frontend portion and a backend portion. The frontend portion includes multiple antennas that supply antenna signals, a first control unit for controlling the frontend portion dependent on control signals received from the backend portion, and a first crossover network that connects a feed line to the first crossover network and the first control unit. The backend portion includes multiple receivers, a second control unit that provides the control signals for the first control unit, and a second crossover network that connects the feed line to the second crossover network and the receivers. The frontend portion is configured to transmit via the feed line antenna signals to the backend portion in a certain frequency range. The backend portion is configured to transmit the control signals to the frontend portion in a frequency range other than the certain frequency range.
